A nurse is caring for a client who is coming in for her first prenatal visit and it is estimated to be 9 weeks gestation.
An ultrasound is scheduled.
The nurse should explain to the client that the ultrasound is being done today to assess for which of the following?
Chromosomal defect.
Fetal lung maturity.
Fetal heartbeat.
Fetal position in utero.
The Correct Answer is C
Choice A rationale
Chromosomal defects are typically assessed using different tests, such as chorionic villus sampling or amniocentesis, rather than an ultrasound at this early stage.
Choice B rationale
Fetal lung maturity cannot be assessed at 9 weeks gestation because the lungs are not yet developed. This assessment is usually done later in pregnancy if preterm delivery is anticipated.
Choice C rationale
At 9 weeks gestation, the primary purpose of an ultrasound is to confirm the presence of a fetal heartbeat, which indicates a viable pregnancy.
Choice D rationale
The position of the fetus in utero is not a concern at this early stage of pregnancy. Fetal positioning becomes relevant later in pregnancy, closer to delivery.

Correct Answer is D
Explanation
Choice A rationale
During pregnancy, the body’s production of red blood cells usually increases to meet the increased demands of the growing fetus. Therefore, a drop in hematocrit is not typically due to insufficient red blood cell production.
Choice B rationale
While iron is essential during pregnancy, a reduction in hematocrit levels at 16 weeks' gestation is primarily due to increased plasma volume, rather than iron deficiency. Nutritional counseling may still be beneficial but isn't the primary explanation for this change.
Choice C rationale
A hematocrit level of 34% at 16 weeks is generally not considered indicative of a severe problem. Instead, it is a physiological response to increased plasma volume, known as dilutional anemia of pregnancy.
Choice D rationale
The primary reason for a lower hematocrit count during pregnancy is the increase in blood plasma volume, leading to dilutional anemia. This is a normal adaptation to pregnancy that ensures adequate blood flow to the fetus.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale
Do not gain more than 25 pounds in pregnancy due to body image issues is incorrect. Gaining an appropriate amount of weight based on individual health and pregnancy needs is important, and it should not be restricted based on body image concerns.
Choice B rationale
Continue to take your prenatal vitamin every day is correct. Prenatal vitamins are essential in providing the necessary nutrients for both the mother and developing fetus, including folic acid, iron, and calcium.
Choice C rationale
Avoid alcohol, tobacco, and drugs is correct. These substances can have harmful effects on fetal development and should be avoided to ensure a healthy pregnancy.
Choice D rationale
Do not eat more than 12 ounces of low mercury fish each week is correct. While fish can be a good source of protein and omega-3 fatty acids, it's important to limit intake of fish that may contain higher levels of mercury to avoid potential harm to the fetus.
Choice E rationale
Increase caloric intake by 100-200 a day is correct. Pregnant teens need additional calories to support their own growth as well as that of the fetus, but the increase should be moderate and balanced with nutritional needs. .
